Your client has moderate noninflamed acne and is not dehydrated. What is the best next step for their home care?

The best next step for a client with moderate noninflamed acne who is not dehydrated is to test the Vitamin A Corrective serum and add it nightly if tolerated. Vitamin A is known for its ability to help regulate cell turnover and prevent the clogging of pores, which is essential in managing acne. This ingredient can also reduce the formation of new acne lesions and improve overall skin texture and tone.

Introducing a Vitamin A Corrective serum into the home care regimen can provide additional benefits that the current products may not be delivering effectively, particularly for moderate acne. However, it is crucial to introduce new treatments carefully and monitor the skin's tolerance to avoid irritation. This approach allows for a more customized treatment plan, ensuring the client receives the added benefits of Vitamin A while assessing their skin's response.

Continuing with the same serum every day or modifying the frequency of application, as suggested in the other options, may not provide the additional therapeutic effects needed to tackle moderate acne issues effectively. Hence, the introduction of a new corrective serum is a proactive measure for better addressing the client's skincare needs.
